ABSTRACT

An inflatable camping mattress for use in the polar region includes an upper body and a lower body. The upper body is stacked on the lower body. The circumferential edges of the upper body and the lower body are sealed to form a separation layer between the upper body and the lower body. The inflatable camping mattress of the present invention can lower thermal conduction by the separation layer. When the present invention is used at the polar region, it can keep out the cold and prevent thermal loss for sleeping.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an inflatable camping mattress for use in the polar region, and more particularly to an inflatable camping mattress which can lower thermal conduction and thermal loss.

2. Description of the Prior Art

Many people like to get close to nature, such as camping. When camping at a place at a lower temperature without good accoutrements, people may feel cold because the earth's surface absorbs heat relative to the human body's temperature. Sometimes, thermal loss may cause a life danger. Therefore, a camping mattress is used to separate temperature for camping, and then the sleeping bag is placed on the camping mattress. This camping mattress must be light for carrying. The conventional camping mattress doesn't have a good effect to separate temperature so it is not adapted for use in the polar region. Some camping mattresses are heavy and not convenient for carrying.

An outdoor camping mattress able to separate temperate is developed, but its structure is too complicated. It is quite troublesome to manufacture, and the camping mattress is heavy. For the user to camp in bad weather or to walk a long distance, it will be a burden. Besides, the complicated structure will result in high cost and high price. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide an inflatable camping mattress which is light, can be manufactured easily, is cost-effective and can prevent thermal loss for bad weather.

For the inflatable camping mattress to isolate temperature, the top and the bottom of the inflatable camping mattress need to lower thermal conduction. The inflatable camping mattress of the present invention is composed of upper and lower parts, and a separation layer is formed between the upper and lower parts. Thus, the temperatures of the top and the bottom of the inflatable camping mattress can be separated effectively to lower the temperature conduction effect.

For the inflatable camping mattress to isolate temperature, the air flow rate inside the inflatable camping mattress needs to lower. The inflatable camping mattress of the present invention is composed of the upper and lower parts which are in an independent relation. Through a plurality of small holes to communicate with each other for air inflation, the internal air of the upper and lower parts is not easy to flow so as to lower the flow rate, preventing temperature loss.

In order to achieve the aforesaid object, the inflatable camping mattress of the present invention is adapted for use in the polar region. The inflatable camping mattress comprises an upper body and a lower body. The upper body is stacked on the lower body. The circumferential edges of the upper body and the lower body are sealed.

The upper body is a closed configuration with a plurality of pressed portions to form upper bladders. The inside of the upper body is able to store air. By means of the pressed portions, the upper bladders of the upper body are connected side by side.

The lower body is a closed configuration with a plurality of pressed portions to form lower bladders. The inside of the lower body is able to store air. By means of the pressed portions, the lower bladders of the lower body are connected side by side.

The upper body and the lower body are in an independent relation. After sealed, the upper body and the lower body have a connecting hole therebetween, such that the upper bladders of the upper body communicate with the lower bladders of the lower body through the connecting hole.

The number of the connecting hole may be one or more than one. The number and diameter of the connecting hole is just for the need of inflation and air release. To prevent the air from bringing thermal energy to flow inside the inflatable camping mattress, the number of the connecting hole is as few as possible and its diameter is as small as possible.

Because the circumferential edges of the upper body and the lower body are sealed, the upper body and the lower body form a separation layer therebetween. Through the separation layer, the inflatable camping mattress of the present invention can lower thermal conduction to keep out the cold and prevent thermal loss.

The inflatable camping mattress further comprises a nozzle. The nozzle communicates with the inside of the inflatable camping mattress. The nozzle is disposed on either of the upper body and the lower body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the present invention discloses an inflatable camping mattress 1 used for the polar region. The inflatable camping mattress 1 comprises an upper body 11 and a lower body 12. The upper body 11 is stacked on the lower body 12. The circumferential edges 15 of the upper body 11 and the lower body 12 are sealed so that the upper body 11 and the lower body 12 become one-piece.

The upper body 11 is a closed configuration with a plurality of pressed portions 112 to form upper bladders 111. By means of the pressed portions 112, the upper bladders 111 of the upper body 11 are connected side by side. The lower body 12 is a closed configuration with a plurality of pressed portions 122 to form lower bladders 121. By means of the pressed portions 122, the lower bladders 121 of the lower body 12 are connected side by side.

The upper body 11 and the lower body 12 are in an independent relation. After sealed, the upper body 11 and the lower body 12 have a connecting hole 13 therebetween, such that the upper bladders 111 of the upper body 11 communicate with the lower bladders 121 of the lower body 12 through the connecting hole 13. The number of the connecting hole 13 may be one or more than one for communication of the upper bladders 111 and the lower bladders 121. To prevent the air from bringing thermal energy to flow inside the inflatable camping mattress 1, the number of the connecting hole 13 is as few as possible and its diameter is as small as possible. Because the circumferential edges 15 of the upper body 11 and the lower body 12 are sealed, the upper body 11 and the lower body 12 form a separation layer 14 therebetween.

The inflatable camping mattress 1 further comprises a nozzle 10. The nozzle 10 communicates with the upper bladders 111 and the lower bladders 121 of the inflatable camping mattress 1. The nozzle 10 is disposed on either of the upper body 11 and the lower body 12.

As shown in FIG. 3, the inflatable camping mattress 1 of the present invention can lower thermal conduction by the separation layer 14. When the present invention is used in the polar region, the human body 3 will lie on the inflatable camping mattress 1. Because the earth′ surface 12 is at a lower temperature, the thermal energy of the human body 3 will be absorbed by the earth's surface 2 easily. The inflatable camping mattress 1 of the present invention has the upper bladders 111 and the lower bladders 121 and the separation layer 14 between the upper bladders 111 and the lower bladders 121. When the thermal energy of the human body 3 is conducted to the upper bladders 111, through the separation layer 14 as a shield and the small contact area between the upper bladders 111 and the lower bladders 121, the thermal energy of the human body 3 won't be conducted to the lower bladders 121 easily. Obviously, the structure of the present invention can lower thermal conduction to keep out the cold and prevent thermal loss.

As shown in FIG. 4, the upper bladders 111 communicate with the lower bladders 121 through the connecting hole 13. The number of the connecting hole 13 is as few as possible and its diameter is as small as possible. In addition, the upper bladders 111 and the lower bladders 121 have respective internal pressure, so the thermal energy is not easy to flow between the upper bladders 111 and the lower bladders 121.

In the aforesaid embodiment, the upper bladders 111 and the lower bladders 121 are aligned with each other. FIG. 5 shows another embodiment of the present invention, the upper bladders 111 and the lower bladders 121 are interlaced each other.

The present invention has a simple structure, can be manufactured conveniently, and is cost-effective and carryon.
